A simple explanation is presented for the large quantitative discrepancies between theory and experiments regarding the effects of tunneling resonances in suitably designed, double-barrier heterostructures. It is suggested that the main limitation is due to the maximum amount of charge that can be accomodated on the resonant level without taking it out of the resonance energy-alignment condition. As this is normally much less than that required for a fully developed resonance, the experimental effects are proportionally reduced. © 1986.

Abstract
A simple explanation is presented for the large quantitative discrepancies between theory and experiments regarding the effects of tunneling resonances in suitably designed, double-barrier heterostructures. It is suggested that the main limitation is due to the maximum amount of charge that can be accomodated on the resonant level without taking it out of the resonance energy-alignment condition. As this is normally much less than that required for a fully developed resonance, the experimental effects are proportionally reduced. © 1986.File in questo prodotto:
